IMPROVEMENT IN SHANK-LASTERS.

Specification forming part of Letters Patent No. 129,301, dated July 16,1872.

To all whom it may concern:

Be it known that I, DANIEL WITT, of Hubbardston, in the county ofWorcester and State oflvlassaohusetts, have invented a new and valuableImprovement in Shank-Lasters; and I do hereby declare that the followingis a full, clear, and exact description of the construction andoperation of the same, reference being had to the annexed drawing makinga part of this specification, and to the letters and iigures ofreference marked thereon.

Figure 1 of the drawing is a representation of a side view oi myinvention. Fig. 2 is a front view of the same.

This invention has relation to shank-lasters for shoemakers use 5 andconsists in the construction and novel arrangement of the serrated jawsand adjustable fulcrumlever, whereby this improvement is adapted todifferent Widths of leather.

Referring to the accompanying drawing, A A represent the serrated jawsby means of which the leather is tightly held. The shanks b b1 arepivoted together, the former being slotted to receive the latter. B Bare the handles by means of which the jaws are operated. The upper partbZ of the handle B is slotted to receive the fulcrumarm C. At D thehandles are pivoted together. To the arms b2 and C are pivoted lthe armsor shanks b b1. The arm C is constructed with a series of holes,

d, by means of which the shank b may be adjusted to different positions.At the end of the arm G is formed a convex foot, D, which lies on a linewith the ends of the jaws and serves as a fulcrum to the shank-laster indrawing the leather over the last. As will be seen, the piece comprisingthe jaw b and its shank is of the form of the letter J, the bot-- tom orcurved part being the jaw. The outer surface of said jaw is grooved andridged so that it may be used as a sole-burnisher. K designates a springfor opening the jaws.

The object of the peculiar arrangement of the jaws and their shanks isto increase the power of the jaws and to give them the most desirableposition for use.

What I claim as my invention, and des-ire to secure by Letters Patent,is-

The shank-laster, consisting of the serrated jaws A A, the former,provided with the jointed shank 111B, pivoted to the adjustable jointedshank `b B' having the adjusting perforations d, substantially asspecified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

DANIEL WITT.
